Hello guys. Whenever I run Yarn test, I get the below error message from the test files. This happens only when I try running tests.

    TypeError: Converting circular structure to JSON
        --> starting at object with constructor 'NestContainer'
        |     property 'modules' -> object with constructor 'ModulesContainer'
        |     property 'InternalCoreModule' -> object with constructor 'Module'
        --- property 'container' closes the circle
        at stringify (<anonymous>)

I can't really tell. I haven't included any custom test. It's just the boilerplate test generated by nestJs.
